The paper by D. T. Son and B. Z. Spivak explores the classical magnetoresistance of Weyl metals, where the electron Fermi surface has nonvanishing Berry curvature fluxes. This system can exhibit large negative magnetoresistance with unusual anisotropy, depending on the angle between the electric and magnetic fields. The authors attribute these phenomena to the chiral anomaly in electron transport theory. They derive the semiclassical kinetic equations and show that the chiral anomaly leads to a significant negative magnetoresistance, which is an increasing function of the magnetic field. Additionally, they find that the system supports a new type of plasma wave with a frequency proportional to the magnetic field and temperature. The analysis is valid for low magnetic fields and high temperatures, where the chemical potential is finite and the Landau quantization can be neglected. The results highlight the unique properties of Weyl metals and provide insights into the behavior of electron transport in materials with nontrivial topological properties.The paper by D. T.
